MAX14578E/MAX14578AE

USB Battery Charger Detectors

General Description

Features

S Compliant to USB Battery Charging Revision 1.1

The MAX14578E/MAX14578AE are USB charger detec-

tors compliant with USB Battery Charging Revision 1.1.

The USB charger-detection circuitry detects USB stan-

dard downstream ports (SDPs), USB charging down-

stream ports (CDPs), or dedicated charger ports (DCPs),

and controlS an external lithium-ion (Li+) battery charger.

S Charging Downstream Detection

S Apple/Sony Charger Detection

S Dedicated Charger Detection

The devices implement USB Battery Charging Revision

1.1-compliant detection logic including data contact

detection, D+/D- short detection, charging downstream

port identification. The MAX14578AE features an enable

(EN) input and an LDO output.

In addition, the internal USB switch is compliant to

Hi-Speed USB, full-speed USB, and low-speed USB

signals. The devices feature low on-resistance, low

on-resistance flatness, and very low capacitance. The

devices also feature high-ESD protection up to Q15kV
